What is Waterproofing?

Waterproofing is a method to resist the effect of incoming water vapours, rainwater, direct water and from other unknown sources on the rooftop of a building, bathroom, kitchen, basement, terrace and any construction area.

A layer is added that acts as a barrier between the water and building material – especially Polyurethane and Cementitious Coating are utilized for making water-resistant membrane.

Waterproofing helps in preventing water from penetrating various parts of the wall, roof and internal areas of a structure. In simple words waterproofing is –

  • To make surface water- restricted – waterproofing is a necessity and a need of every building.
  • The procedure is done simply by making a layer or coat of a particular material over the top of the existing surface area.
  • It protects the portion from humidity and damping by keeping it dry, fresh and balanced.
  • By waterproofing, the whole house can be saved from the harmful effects of water exposure such as – damage to furniture, wall paints, home accessories, unwanted odour and cracks in ceilings.
  • To maintain the integrity of a structure – waterproofing is done layer by layer by forming multiple barriers among the base constructional materials.
  • Though waterproofing is vital for all areas nearly connected to the water yet the basement is the most crucial portion and must be coated well with proper care.


Many people often call Waterproofing water resistance though we cannot admit the person wrong. Both the words are closely linked to each other and people also accept its usage at the place of waterproofing. Nonetheless, we are here to clarify the true meanings.


A Water resistance material will catch and does not let the water enter the material till a specific point. Ultimately, this will give a good layer and coating to material for resisting water to move in certain parts of an item. Material resistance to water can withstand splashes and drops of liquid but cannot promise safety when submerged in the water.


On the other hand, the next level of water resistance material can be known as Waterproofing. A waterproof material completely guards the surface against entering the liquid. The Ingress Protection rating (IP code) defines the calibre of an item to which it can stand the water. A device or material with waterproof property can be easily dipped into the water.


The basic idea of the whole concept is to ensure the safety and good condition of the structure by keeping it preserved from the contact of water. We often deal with leaking roofs, damping rooms, dripping edges, this happens due to the lack of a guarding layer. It occurs not immediately but gradually over a certain period by changing climate conditions.

The result of damp, wet and humid walls, roof and floors can be scary. Read below the major points conveying the importance of waterproofing.

  1. The building becomes weak and can create trouble while certain weather conditions such as rainfall, flood, tsunamis, earthquake and including many other unfortunate events.
  2. The worse – Crakes, brakes and holes may be appearing gives rise to tiny and huge insects. Also, it opens the ways for surface water to enter the building.
  3. Painted walls become messy and can be seen chapping layer by layer with humidity present between the walls. Similarly, without protective film – the floor set off to be unusually wet in monsoon season.

In construction, the method of preventing the arrival of water from a small or big crack and by absorption is popularly known as Waterproofing. It helps in enhancing the efficiency and life span of material by making it seamless, functional and suitable for all weather conditions. Need for every bathroom, toilet, swimming pool, water tank, reservoirs, dams and any kind of materials.
